The objective was to evaluate the effect of concentrate supplementation using by-products of the Amazonian industry on milk production, milk composition, and milk fatty acid profile of dairy buffaloes. Twelve lactating buffaloes (544.5 AE 35.6 kg, 6.4 AE 2.2 years old, 59 AE 6 days in milk) were allotted in a pasture of Mombaça grass and managed under rotational grazing (4 days occupancy/28 days rest). A 3 Â 3 Latin square was adopted, and each animal alternately received three supplementary treatments based on corn bran + soybean meal or cupuaçu cake or murumuru cake for 21 days per treatment. Murumuru cake increased the levels of lauric acid and myristic acid in the milk (p < 0.05). Murumuru cake reduced the unsaturated fatty acid contents in the milk compared with animals fed control diet or cupuaçu cake (24.27% vs. 25.24% vs. 25.08%). The n-6/n-3 ratio was 2.6, 1.97, and 2.0 in the control, cupuaçu, and murumuru groups, respectively. Based on this parameter, cakes made from cupuaçu as well as murumuru could be considered to be adequate for inclusion in dairy water buffalo feed. However, the murumuru cake addition requires some caution because its use induces the secretion of higher levels of lauric and myristic fatty acids that are related to human cardiovascular disease.
The study aimed to assess the food accessibility and consumption among families in the Cupiúba rural settlement, in the city of Castanhal, Pará, Brazil. It was found that the access to food is worrying and indicated that most families are in food insecurity conditions. Moreover, income and food safety level were associated. The consumption of the settler families comprises mainly high-energy, low-nutrient content foods, characterized by the low intake of fruits and vegetables and the introduction of processed foods with high energy density and sugar-added beverages, although the traditional dietary habits (rice and beans) are still present. This configures a diet at risk for important nutritional deficits, obesity, and many non-communicable chronic diseases.Keywords: access; food consumption; settlement.Practical Application: Most families studied are in food insecurity conditions and food consumption comprises mainly high-energy, low-nutrient content foods, characterized by the low intake of fruits and vegetables and the introduction of processed foods with high energy density and sugar-added beverages, although the traditional dietary habits (rice and beans) are still present.

O vigente estudo apresenta como principal objetivo avaliar a qualidade higiênico-sanitário e a composição nutricional do leite in natura produzido no laboratório de leite do Instituto Federal do Pará -Campus Castanhal. O leite in natura foi coletado no setor de bovinocultura do IFPA-Campus Castanhal, respeitando o horário de ordenha pela qual os animais diariamente são ordenhados e as boas práticas de fabricação de alimentos (BPF). As coletas seguiram um cronograma, onde eram avaliados de quinze em quinze dias os respectivos parâmetros físico-químicos: gordura (%), sólidos não gordurosos (%), densidade (kg/m3), ponto de congelamento (ºC), condutividade (ms/cm), proteína (%), lactose (%), sólidos (%), água adicionada (%) e temperatura (ºC), pH e ATT (%). Por fim, as amostras foram coletadas a cada 30 dias, sendo submetidas a análises de Coliformes Totais, Coliformes Termotolerantes e Contagem de microrganismos Aeróbios, visando determinar a sua qualidade microbiológica.
